2.23 Watchman

2.23.1 How watchman works

The watchman function periodically transmits radar pulses for one minute to check for targets in a guard zone. If a target is found in the zone, watchman is cancelled, the audio alarm sounds and the radar continues transmitting. If no target is found the radar goes into standby for the number of minutes specified on the RADAR DISPLAY SETUP menu. This feature is useful when you do not need the radar’s function continuously but want to be alerted to radar targets in a specific area. “WTCH” appears at the top left corner when Watchman is active.
